RE: fmu or regulater?

As far as i know, a FMU hooks up to your FPR. It "lies" to the fuel pressure regulator to give more fuel pressure to the regulator in order to get more fuel into the engine. Usually FMUs are used with a turbo application. If your FPR does not fit, you might have the wrong regulator so call the manufacture and see if its the right one.
